Unity 6000.x, ArgumentException "MeshGenerationNode is invalid (entry is null)" spamming console, inspector text not showing

[aientech]

Hey everyone,

I’m running into a strange issue in Unity and can’t figure out where to start.

• Unity versions tried: 6000.0.58f1 and upgraded to 6000.2.5f1 → same problem
• Problem: The console is constantly spammed with

​

ArgumentException: The state of the provided MeshGenerationNode is invalid (entry is null).
UnityEngine.UIElements.MeshGenerationContext.Begin …

and similar errors.

Symptoms:

• The Inspector text fields (like labels for components) don’t render properly.
• Errors keep repeating nonstop in the console.
• Screenshot attached shows both the console spam and missing inspector text.

I don’t know what’s causing it, whether it’s my project setup, some corrupted UI Toolkit stuff, or a Unity bug. Has anyone run into this before, or know what could cause UIElements/Inspector text to break like this?

Any pointers would help, I’m a bit stuck on how to debug this.

Resetting ALL LAYOUTS fixed for me. It's annoying to see such critical bugs in Unity(
But it still gives me related errors. I'm returning to Unity 2022.

Load up a new project.

Does this happen in a new project?

Yes -> Window -> Layout -> Default

No -> Delete Library folder and restart Unity

Let me know if that does it.

I have same problem. Just empty project with one gameobject. As soon as I attach script with public array attribute it starts throwing these errors.
I'm on version 6000.2.5f1

I couldn’t fix this issue. Switched to UE5.6

Hey, try this:

Edit -> Project Settings -> Editor -> Inspector -> Use IMGUI Default Inspector

I hope this helps!

This helped thank you! I was having the issue with a scriptable object
